- PROCESS FOR PREPARING DIARYL ALKYLPHOSPHONATES AND OLIGOMERIC/POLYMERIC DERIVATIVES THEREOF
-
A process is provided for the production of diaryl alkyl phosphonate by the reaction of triaryl phosphate with dialkyl alkyl phosphonate in the presence of alkali metal iodide catalyst; and, optionally, the diaryl alkyl phosphonate is reacted in situ with

- LES PHOSPHORANES MONOCYCLIQUES A LIAISON PH DANS LES REACTIONS DE REDISTRIBUTION DE LIGANDS DES COMPOSES DU PHOSPHORE TRICOORDONNE
-
The oxidative addition of alcohols and amines with 2-alkyl, 2-aryl, 1,3,2-dioxa, oxaza or diazaphospholanes, leads to a ring opening reaction and ligands exchange around the phosphorus atom by alcoholysis or aminolysis of P-O or P-N bonds.In nearly all cases, monocyclic phosphoranes with P-H bond have been detected in an intermediate step during the exchange of one tricoordinate form to another one.At last we have discussed the phorpholanyl ring stability. - Key words: 1,3,2-Dioxaphospholanes; 1,3,2-oxaza-phospholanes; 1,3,2-diazaphospholanes; Monocyclic phosphoranes with P-M bonds; phosphoranyl ring stability.
